I've had several people do a combined translation of Starbound, chapter 1, into Japanese. I've got one of them on chapter 2, but if you go to Upwork, the other one's name was Gaynor Champion. See if she'd be willing to lend a hand, or whoever else would be.

You can also look for Aaron Vincent Vergara, whom I once had translate something from the original Puella Magi Madoka Magica mobile game.
